Member of audience set out in passenger ship (8)
I believe the answer is:
listener
'member of audience' is the definition.
(I've seen this before)
'set out in passenger ship' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'in' is an insertion indicator.
'passenger ship' becomes 'liner' (I've seen this in another clue).
'set' with letters rearranged gives 'ste'.
'ste' placed inside 'liner' is 'LISTENER'.
(Other definitions for listener that I've seen before include "Radio fan" , "One pays attention in order to hear" , "One who hears" , "Someone paying attention" , "One hearing" .)
